Bonaire diving is definitely not boring. I just got back from a stay with Buddy Dive and the diving was phenomenal. The diversity of life and health of the corals is second to none.
The dives are not all the same. At the southern end, you will experience dives with a longer terrace before you hit the reefs; great areas for eagle rays, squid squadrons (saw 42 in a perfect line on the terrace of Alice in Wonderland). Many of these dives are also a double reef system, with a small terrace around 80-90 feet leading to a second reef. The fish life on the southern end is amazing; I was normally accompanied by a never-ending school of creole wrasse.
The dives on the northern end allow you to practically drop straight in on the reef. Oil slick leap was one of my favorites. Regardless, all of these sights are bursting with marine life. Loggerheads, hawksbills, longlure frogfish, morays and spotted eels, seahorses, and the like are found throughout the reef system.
Night diving is first-class. My night dives were on Buddy's reef or other nearby, centrally-located reefs. I was accompanied by very large tarpon on all of these dives (which frequently cruised by within arms reach). Octopus, green and spotted morays, large porcupine fish, lobster and the like can be expected.
Buddy Dive Resort was great. The drive-up tank refill is very diver-friendly. The staff was incredibly helpful, and the house reef is a good dive in itself. Our condo was about 75 feet from the ocean, very convenient and a great view.
Bonaire is more micro diving. You could spend almost an entire dive closely examining a 50 ft. square grid and still miss something. It's slow, observant diving. Perfect your buoyancy and closely examine the reefs, you'll be amazed what you can find if you pay attention.
The East Side of the island offers better chances to dive with some of the bigger pelagics. Look into Larry's Wild Side Diving. Conditions can get a little rough at times, but he'll take you out there.
Klein Bonaire is a small island across from Bonaire. Some great boat dives are done here.
You should also spend one day in Wahington Slagbai National Park. Some amazing scenery. The north end leads you to the sheef cliffs of fossilized coral and rough surf at the island's edge, and the interior is a desert-scrub habitat and equally beautiful. Birding is cool here, too. I got some nice pics of a Caracara (desert, hawk-sized raptor) which let me approach quite closely as it was perched on a cactus.
Believe me, give Bonaire a shot, you won't disappointed. You'll love it, below and above the water. Where else can you load your truck, drive around a beautiful island, chose one of 60 or so sites, and drop into a world-class reef system? It's 24 hour-a-day diving that you just can't beat.
